Fueling the Future: Advancing Cetane Testing Technologies
this transition is the development and commercialisation of novel Sustainable Aviation Fuel (SAF) technologies. The CFR Ignition Quality Tester (IQT®) has been at the forefront of advances in SAF formulations since their inception.
Jet engine researchers using the IQT discovered that the Derived Cetane Number (DCN) measured by IQT had applications beyond diesel fuel; the DCN of prototype synthetic jet fuels could identify if they were more likely to experience lean blowout than conventional petroleum jet fuels. During a lean blowout event the flame in a jet engine literally blows out: not a good thing while flying! ASTM D4054, the Standard Practice for Evaluation of New Aviation Turbine Fuels and Fuel Additives, is used worldwide to screen candidate SAF formulations for compatibility with conventional jet fuel properties. D4054 requires a DCN value of 35-60 (to avoid lean blowout), and IQT test method D6890 is the only test method recognized by D4054 for this purpose.
In pursuit of reductions in greenhouse gas emissions, there have been substantial shifts from internal combustion engines to battery electric powertrains for passenger cars and light trucks. However, other sectors of the transportation industry such as long-haul trucking and aviation are inherently unsuitable for electrification and will remain reliant on liquid hydrocarbon fuels for the foreseeable future. Fortunately, it is possible for liquid fuels to have net-zero carbon emissions if they are produced from renewable feedstocks. The adoption of such sustainably produced diesel fuels and jet fuels is critical to efforts to reduce greenhouse gas emissions from these sectors.
The aviation industry is moving towards the achievement of net-zero carbon emissions at an unprecedented rate. The key to
In the world of SAF development, potentially game-changing fuel formulations are often initially available only in tiny quantities from research programs. Thus, one critical need for SAF researchers is the ability to conduct the required DCN tests using relatively small sample volumes. The IQT meets this need with the lowest sample volume capabilities in the industry. A full IQT fuel reservoir contains 30 mL of sample, which provides enough fuel for 3 replicate tests with a typical jet fuel. The IQT fuel reservoir can also be partially filled, and a single D6890 DCN test can be run with only 10 mL of sample.
In ground transportation, the IQT is the leading cetane testing technology for sustainable diesel fuels such as renewable or “green” synthetic diesel. IQT test method EN 15195 is the referee test method for cetane in EN 15940, the European Standard for Diesel Fuels from Hydrotreatment and Synthesis. This standard includes renewable diesel fuel and diesel fuel from Gas-to-Liquids (GTL) processes. The IQT has continually improved since it was adopted by the petroleum industry over 27 years ago, and the latest model, the IQT-XLM, is now in service in North America, Europe and Southeast Asia.
The CFR F5 Cetane Rating System remains the referee test method for petroleum diesel, FAME biodiesel, and petroleum/ biodiesel blends. The F5 Engine technology has vastly improved over the legacy engines that have served the fuel industry for many decades. The F5 Cetane EFI Rating System now brings Electronic Fuel Injection to the ASTM D613 test method, offering substantial improvements in test-to-test repeatability and the ability to test biodiesel without the need for injection nozzle cleaning.
Cetane EFI improves ease of use such that inexperienced operators can quickly learn to achieve consistent results. It is also more suitable for research applications, as full D613 CN tests can now be run with less than 500 mL of sample. ASTM D613 will soon include Cetane EFI as Procedure B of the test method. Procedure B has been approved by the subcommittee responsible for D613, and publication of the revised test method is expected shortly.
Already generating excitement, the first Cetane EFI engine in refinery service was commissioned earlier this year, signaling a new era of precision for the venerable cetane engine.

and eliminates the complexities. Additionally, PMH is less prone to peroxide formation, increasing safety and reducing waste. The result is a more cost-effective, high-performing fuel standard that aligns with renewable diesel needs, which often require cetane levels above those of SRF T.
CFR Engines, Inc. (CFR), a world leader in the design and manufacturing of Octane, Cetane, Ethanol, and Aviation fuel rating test instruments — and Monument Chemical — a custom manufacturing company serving the specialty chemicals industry on a global scale are partners committed to sustainable innovation in fuels. This partnership marks a significant step in advancing the use of PRFs, such as Pentamethylheptane (PMH) and Hexadecane (HD), which were launched in 2016 by Monument Chemical to drive the vision of replacing SRFs with cleaner, more reliable alternatives.
Historically, the industry has relied on the Secondary Reference Fuel (SRF) T and U pairs, which require complex production and validation every one to two years, often involving scarce and costly heptamethylnonane (HMN) to calibrate these batches. As pure compounds, PMH and HD maintain stable cetane values over time, minimizing the inconsistencies that come with blended SRFs. This stability allows for more accurate CN measurements
Additionally, PMH, produced in large quantities at a reasonable cost, can directly replace SRFs T and U as a standard for CN and DCN measurement, eliminating the need for costly and time- consuming batch recalibration.
As sustainable alternatives, PMH and HD as replacements for SRFs T and U offer a more sustainable and efficient solution for Cetane Number (CN) and Derived Cetane Number (DCN) measurement, aligning with ASTM standards D613 and D6890.
According to Indresh Mathur, Director of Innovation and Customer Solutions at Monument Chemical, “PMH exemplifies our dedication to renewable fuels and innovative chemical solutions. Unlike SRFs T and U, PMH and HD are pure compounds, providing stability for over 10 years and reducing waste, making them ideal for the industry’s shift toward renewable diesel.”
Tedd Zebrowski, President at CFR Engines Inc. commented, “as the exclusive distributor of PMH through Haltermann Solutions™, CFR is providing a sustainable total customer solution that promotes increased safety and improved performance and efficiency.
“With some companies still hesitant to switch to PRFs, our partnership with CFR ensures a smooth transition and addresses customers’ logistical and technical concerns,” said Joe Latorre, National Accounts Manager at Monument.

Beyond PRFs, CFR and Monument also offer a range of Check Fuels for Octane and Cetane measurements, enhancing quality control and accuracy. Monument is actively working to develop these fuels from sustainable feedstocks, further solidifying their commitment to eco-friendly solutions.
Together, CFR and Monument are paving the way for a more sustainable future in the diesel fuel industry. Their collaboration not only sets new standards for CN and DCN measurement but also positions them as leaders in renewable fuel solutions. As the exclusive provider of PRFs, these partners are uniquely equipped in helping the energy industry transition toward sustainable options, reducing carbon footprints, and driving global environmental progress.
